To further prevent vibrations from reaching the rider and to compensate for .or absorb shocks'due. to uneven roadways, I mount above the said chassis also on opposite sides of said wheel and engine, addltional velucle springs 1,717 and bridging these springs as close to the top of the wheel 2 as posslble, I'provide a wide seat 18,." The springs 17- 17 are. as shown, connected to the chassis or""l )ody' port1on, .which consists roundor circular tubing of the ordinary "typejfby the use of filler strips 13 and 13" as illustrated in Fig. 4.

The fuel. tank 19, asshown, is retained atlth'e' back' of the seat 18 by brackets and straps 19 and 19". The connection between the tank 19 and carbureter 0f the engine is madeby a'flexible tube, and the engine is, as shown controlled byacontrolling device 21 mountedi'fon' the handlebars and con-s said controlling. device 21 jbeing manipulated to control the1 throttle valve of the engine and also-to relieve 'tl1e conipressi0n so that it may be started byritnning the ground wheel J along the roadway,'jand this may be readily StOIL;
